Abstract

The jet-jet profile methods that we developed to enhance the heavy
Higgs to ZZ signal over its backgrounds at a proton-proton
collider energy of 40 TeV are extended to the heavy
Higgs to WW signal and backgrounds.
The dominate background is now the pair
production of top quarks via the subprocess gg to t-tbar. The
process qg to Wq also contributes significantly, and backgrounds from the
production of top quarks via the subprocess bg to Wt and WW continuum
are also included in the analysis but are less important.
To enhance the signal, a
profile analysis is performed on both the &quottoward-side&quot
(the W to lepton-neutrino trigger side) and on the
&quotaway-side&quot (the W to jet-jet system). We define observables that
help distinguish between the transverse energy distribution
of the signal and of the backgrounds in a electromagnetic/hadronic
calorimeter system. By making cuts on both the toward and
away-side observables, signal to background enhancement factors
around 1,000 can be obtained.
